KMT36H 360°
Magnetic Angle Sensor
SPECIFICATIONS
AMR Sensor with 360° capability TDFN outline 2.5x2.5x0.75 mm3 Three 120° phase-shifted signals Moderate field strength requirements
The KMT36H is a magnetic field sensor utilizing the anisotropic magneto resistance effect. Therefore the sensor is sensing the magnetic field direction rather than the magnetic field strength. The sensor contains three Wheatstone bridges rotated by 120°. A rotating magnetic field (typical strength 25 kA/m in the sensor plane) will result in three sinusoidal output signals with a period of 180°, phase shifted by 60° field angle. By use of a modified atan algorithm the field angle can be calculated with high accuracy.
